窗体cs代码

 using System.Collections.Generic;
 using System.Windows;

 namespace ComboxBinding
 {
     /// <summary>
     /// MainWindow.xaml 的交互逻辑
     /// </summary>
     public partial class MainWindow : Window
     {
         public MainWindow()
         {
             InitializeComponent();
         }

         private void Window_Loaded(object sender, RoutedEventArgs e)
         {
             List<ComboxBind> lstCmbBind = new List<ComboxBind>();//用于绑定数据源

             //初始化数据源
             ComboxBind cbb = new ComboxBind("显示值1", "选取值1");
             lstCmbBind.Add(cbb);
             cbb = new ComboxBind("显示值2", "选取值2");
             lstCmbBind.Add(cbb);
             cbb = new ComboxBind("显示值3", "选取值3");
             lstCmbBind.Add(cbb);

             this.comBox1.ItemsSource = lstCmbBind;
             comBox1.DisplayMemberPath = "CmbText";//类ComboxBind中的属性
             comBox1.SelectedValuePath = "CmbValue";//类ComboxBind中的属性
         }
     }
 }

用于绑定combobox的类

 namespace ComboxBinding
 {
     /// <summary>
     /// 用于Combox数据绑定
     /// </summary>
     class ComboxBind
     {
         //构造函数
         public ComboxBind(string _cmbText, string _cmbValue)
         {
             this.cmbText = _cmbText;
             this.cmbValue = _cmbValue;
         }

         //用于显示值
         private string cmbText;
         public string CmbText
         {
             get { return cmbText; }
             set { cmbText = value; }
         }

         //用于实际选取的值
         private string cmbValue;
         public string CmbValue
         {
             get { return cmbValue; }
             set { cmbValue = value; }
         }
     }
 }
